Kharg Island Gas Gathering and NGL Recovery Project (Interconnecting)

The Kharg Island Gas Gathering and NGL Recovery Project is a strategic development in Iran’s oil and gas sector, initiated to enhance the collection, treatment, and export of valuable hydrocarbons from both onshore and offshore fields. Contracted by the Iranian Offshore Oil Company (I.O.O.C), this ambitious onshore project is executed by IRITEC and IRASCO under a full EPC (Engineering, Procurement, and Construction) mandate. The project addresses the need for advanced gas gathering, compression, NGL (Natural Gas Liquids) recovery, and efficient export infrastructure on Kharg Island, one of Iran’s main energy hubs in the Persian Gulf.

The scope of the project includes the construction of extensive pipeline and reception facilities, state-of-the-art onshore gas compression stations, dual NGL trains for the recovery of natural gas liquids, robust NGL storage solutions, and modern export terminals. By gathering gas from both onshore and offshore production sources, the facility is poised to maximize resource utilization and enhance Iran’s petrochemical export capability.

Project Scope and Engineering Services

The NGL recovery facility is a newly developed project, featuring the simultaneous construction of two independent gas treatment and NGL recovery plants. These plants are designed to operate in parallel, sharing essential utilities and a common liquid export system, thus ensuring operational efficiency and flexibility. The process is fed by a mix of onshore and offshore gas streams, enabling steady supply to both domestic and international markets.

John Brown Hydrocarbons: Provided the Basic Engineering and FEED (Front-End Engineering Design) for the onshore facilities, ensuring a solid technical foundation for detailed execution.
Tehran Raymand Consulting Engineers: Contracted by IRITEC, Tehran Raymand is responsible for the detailed design of the common system and all interconnecting services, encompassing project management, interface coordination, and procurement engineering for shared facilities.

Tehran Raymand’s work covers the engineering and integration of all pipelines, utilities, process control systems, and shared support infrastructure that connect the major process units and support seamless, safe plant operation.

Process Units and Major Facilities

1. Reception Facilities: Initial intake and handling of gas streams received from multiple onshore and offshore sources, ensuring controlled flow and metering into the plant.
2. Compression Stations (1 & 2): High-performance compression units to raise the pressure of incoming gas, enabling efficient downstream processing and NGL extraction.
3. Acid Gas Removal Units (1 & 2): Advanced treatment trains to remove hydrogen sulfide (H₂S), carbon dioxide (CO₂), and mercury. Includes dehydration systems to protect downstream equipment and improve gas quality.
4. NGL Recovery Units (1 & 2): Dual units dedicated to the separation and recovery of natural gas liquids (NGLs), maximizing hydrocarbon recovery and plant profitability.
5. Utility Systems: Comprehensive infrastructure supplying power, water, compressed air, and other utilities critical for uninterrupted plant operation.
6. Storage Tanks: Secure storage facilities for processed NGLs and other by-products, equipped with safety and monitoring systems for reliable product handling.
7. Acid Gas Injection: Safe, environmentally responsible disposal of acid gases through deep well injection, minimizing atmospheric emissions and supporting regulatory compliance.
8. Seawater System: Seawater intake and distribution for cooling and process needs, leveraging Kharg Island’s strategic location in the Persian Gulf.

The successful completion of the Kharg Island Gas Gathering and NGL Recovery Project will significantly boost Iran’s gas treatment and export infrastructure, supporting sustainable resource management and reinforcing Kharg Island’s role as a key energy export hub.
